2. NetLink Wireless Telephone Overview
The NetLink e340/i640 Wireless Telephone is a mobile handset for workplace IP
telephone systems. The handset operates over an 802.11b wireless Ethernet LAN
providing users a wireless voice over IP (VoIP) extension. By seamlessly integrating
with the Cisco CallManager, handset users are provided with high-quality mobile
voice communications throughout the workplace. The handset gives users the
freedom to roam throughout the workplace while providing all the features and
functionality of an IP desk phone.
The NetLink e340/i640 Wireless Telephone provides a wireless extension to Cisco
CallManager v3.08 and later. The NetLink e340/i640 Wireless Telephone supports
the Skinny Client Control Protocol (SCCP). “Skinny” is an open protocol developed
by Cisco Systems for communication between an IP phone and the CallManager call
processing application. The handset can also be registered to other platforms
supporting SCCP, such as CallManager Express (CME) and Cisco SRST.
The handsets reside on the wireless LAN with other wireless devices using Direct
Sequence Spread Spectrum (DSSS) radio technology. The handset radio transmits
and receives packets at up to 11Mb/s.
A CallManager template for the handset must be configured for the specific features
and lines to be accessed by the handset. The handset can be automatically added to
the network and registered with CallManager, or each of these steps can be
configured manually. After the handset is registered it receives its configuration
information from CallManager.
2.1 QoS and Security
The NetLink SVP Server is an Ethernet LAN device that works with the access
points (APs) to provide QoS on the wireless LAN. Voice packets to and from the
NetLink Wireless Telephones are intercepted by the NetLink SVP Server and
encapsulated for prioritization as they are routed to and from an IP telephony server
or gateway. See the SpectraLink 8000 SVP Server: Administration Guide for Mitel
and Cisco document for detailed information about this device.
The NetLink e340/i640 Wireless Telephone supports Wired Equivalent Privacy
(WEP) as defined by the 802.11 specification. SpectraLink offers the product with
both 40-bit and 128-bit encryption.
NetLink Wireless Telephones support basic WMM™ (Wi-Fi Multimedia) if also
supported by the AP as part of the 802.11e protocol. If the AP supports WMM, the
handset automatically discovers and uses it. WMM does not replace the NetLink
SVP Server as described in the following paragraph. WMM settings must be
configured on the SVP Server.
NetLink Wireless Telephones also support the 802.11i protocol including Wi-Fi
Protected Access (WPA™ and WPA2™)—PSK. As vendors introduce APs that are
eligible to become Wi-Fi CERTIFIED™ for WPA-PSK and/or WPA2-PSK,
SpectraLink will determine their compatibility with the NetLink Wireless Telephones
and include them on the Polycom WLAN Compatibility Table.
